摘要：
The objective of this trial was to evaluate the behavior ingestive of crossbred heifers and chemical characteristics of the material from two clones of dwarf elephant grass (BRS Kurumi 'and CNPGL 01/03/00) submitted to different management strategies through sampling of forage (whole plant extrusa and manual hand plucking. The experiment was conducted at Embrapa Dairy Cattle, Coronel Pacheco, MG. We used a completely randomized design with factorial (2x2x2) with three replications. The treatments consisted of two clones of elephant grass (BRS Kurumi 'and CNPGL 01/03/00), two light interception at the entrance of the animals (90 and 95%) and two heights of post-grazing residue (30 and 50 cm) with three replications. The chemical analysis showed that the methodology manual grazing simulation enables an acceptable estimate of the forage selected by grazing animals and the sampling of the whole plant is not selected by the animal diet. To harvest extrusa rate evaluation and mass bit, fractions and chemical composition of the plant of the ingested material was taken. Characteristics, structural and nutritional value of clone BRS 'Kurumi' facilitated greater forage intake by the animal, suggesting its use in grazing systems.
